2 days ago, an old friend dm’d me on Instagram. I met him back in 2015 over the summer at a college prep camp and we were really good friends throughout the e camp and I did end up crushing on him back then and felt the same vibe from him. Unfortunately after our end of summer trip, we kinda fell off and that was 7 years ago. So he dm’d me on ig 2 days ago (we follow each other) after I posted an October photo dump on my story. We caught up briefly and the convo held for about 2 days. It reminded me of how much I liked him and based on the convo, I don’t want to read too much into it and assume he was flirting bc he could’ve just been being nice and friendly. Not to mention that I sent the last message of the convo and all he did was read it and heart it. Based on the convo below, what do you think? Should I pursue?
